SEE CIFICATION forming part of Letters Patent No. 758,615, datedMay 3, 1904.

I Application filed March 9, 1903. Serial No. 146,848- (N0 model-) To all whom it may concern:

7 Be it known that 1, WILLIAM 0. BROWN, a citizen of the United States, residing in the borough of Richmond, city of New York, county of Richmond, and State of New York, have invented certain new and useful Improvements in Condenser Systems, fully described and-represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to an improved condenser of that class used for the purpose of condensing exhaust-steam of steam-engines and the like and known as elevated injector or jet condensers, the especial object of the invention being to secure a more eflicient action than heretofore and avoid loss of vacuum between the condenser and the engine.

The invention provides for the free unrestricted exhaust of the steam to the condenser, so that the full vacuum is secured at the engine and the efliciency of the steam action therein increased, and this result is secured with a simple and compact. arrangement of the condenser and exhaust-steam piping.

The invention includes certain features of construction and combinations of parts for attaining the above result and novel means by which the objectionable results of expansion and contraction are avoided, all as fully described hereinafter and specifically pointed out in the claims.

For a full understanding of the invention a detailed description of a construction embodying all the features of the same as applied in their preferred form will now be given in connection with the accompanying drawings, forming a part of this specification, in which- Figure 1 is a diagrammatic elevation of a condensing system embodying the invention with the hot-well and the lower portion of the construction shown in section for purpose of illustration. Fig. 2 is a central vertical section taken through the condenser.

In the drawings, A is the condensing-chamber, which in the condenser shown is approximately cone-shaped and commonly called the condenser-coneg B, the exhaust-steam pipe,

to which the steam from the engine or other steam apparatus is delivered through the exhaust-pipe O and which forms a chamber surrounding and extending over the condensercone.

D is the condensing-water pipe, .shown as supplied from the pump E, and F an aircooler, which is preferably inserted in the condensing-water pipe D and from which the air is drawn ofl by the air-pump G.

The condenser tail-pipe H terminates in the hot-well I, preferably being supported by the cone A at its upper end and free to expand at its lower end, as described hereinafter.

A pump K may be provided, as shown, connected to the lower end of the exhaust-pipe B and operated intermittently to withdraw any water that may collect above the hot-well, and a drain-pipe L is provided for drawing oif any water condensed from the vapors in the air-cooler F.

The condensing-water from the pipe I) is delivered through an annular chamber 10 and the usual adjustable spray-valve 11 into the interior of the cone A, the steam entering the space within the cone and inside the spray through the valve 11. The air with the uncondensed vapors are drawn off from the cone through air-pipe 12, opening just below the valve 11 and provided with the hood 13 to prevent water entering the pipe.

The condenser-cone A, with the tail-pipe H extending downward from it, is preferably supported at its upper end on the surrounding steam-pipe B and its lower end left free, so that the pipe shall be free at its lower end for expansion and contraction and all strain on the condenser be avoided, As shown, the cone is supported by adjusting-screws 14 on I the joints at the upper or supporting end of a flange 15 on the inner side of the pipe B,

the annular chamber 10 being provided with a side pipe 16, through which the condensingwater from the pipe D enters. The tail-pipe 'H passes through the cover of the hot-well through a joint, which may be made air-tight by packing or by an expanding metal joint 17, as shown.

The main invention consists in the arrangement for delii'ery of the exhaust-steam to the condenser, and it will be understood that this is applicable to condensers in which the condensing-water is introduced otherwise than as shown and that the details of the condenser construction and the means for supplying and spraying the cond ensing-water may be varied, as desired. While an air-cooler or supplementary condenser is preferably used, as this aids materially in securing the eflicient vacuum desired, it will be understood that the steam-pipe arrangement may be used without such an air cooler or supplementary condenser and that the latter when used and its connections to the condensing-chamber may be of any suitable form other than that shown.

What I claim is 1. The combination with the condensingchamber and tail-pipe, of the vertical exhauststeam pipe inclosing the tail-pipe and condensing-chamber.

2. The combination with the condensingchamber and tail-pipe, of the vertical exhauststeam pipe inclosing the tail-pipe and condensing-chamber, and means for supporting the condensing-chamber and tail-pipe at the upper end of the exhaust-steam pipe with the lower end of the tail-pipe free for vertical expansion and contraction.

3. The combination with the condensingchamber, of an annular chamber inclosing and extending over the condensing-chamber and through which the exhaust-steam is admitted, and an air-pump and connections between the condensing-chamber and air-pump for removing air from the condensing-chamber.

4. The combination with the condensingchamber, of the exhaust-steam pipe extending upward from below the condensing-chamber and forming an annular chamber inclosing and extending over the condensing-chamber and through which the exhaust-steam is admitted, an air-pump and connections between the condenser and air-pump for removing air from the condensing-chamber, and a surface-cooler and cooling-liquid connections therefor between the condenser and air-pump.

5. The combination with the condensercone A, of the steam-exhaust pipe B forming an annular chamber surrounding and extending over the condenser-cone, condensing-water pipe D, and annular chamber 10 and a sprayvalve for spraying the water into the steam.

6. The combination with the condensercone A, of the steam-exhaust pipe B forming an annular chamber surrounding and extending over the condenser-cone, condensing-water pipe D, annular chamber 10 and a spray-valve for spraying the water into the steam, airpipe 12 within the cone, an air-pump for withdrawing the air from the cone, and a surfacecooler within the pipe D between the cone and air-pump through which the air passes to the air-pump.

7. The combination with a condensingchamber and hot-well, of the condenser tailpipe H supported by the chamber and entering the hot-well through a joint permitting its vertical expansion and contraction, and the vertical exhaust-pipe B inclosing the condensing-chamber and tail-pipe and supporting the condensing-chamber.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
